Purpose
Abstract The cruise aimed to conduct shallow drilling at three previously identified hydrothermal vent sites using a lander-type drilling device and the British Geological Survey.Research focused on two main areas,namely a massive sulfide occurrence at the Palinuro volcanic complex and shallow marine sulfate deposits forming offshore Panarea Island.Extensive seafloor mapping was conducted using the EM120 multibeam obtain high-resolution bathymetric maps of the Palinuro and Marsili volcanic complexes. In addition, the seafloor surrounding Panarea Island was surveyed to add to the existing shallow water. The EM120 multibeam system consisted of 2 transmitter/receiver units coupled with a motion reference unit. The system was set at an operating frequency of 12kHz, with a 2x30° opening angle and 191 simultaneous beams per ping. Cruise M73/2 provided the first detailed bathymetric survey of the Palinuro volcanic complex.
